1. The words in the original are anzalana hu: "We Ourself have sent it down". But although there is no mention of the Qur'an before it, the Qur'an is implied, for "sending down" by itself points out that the Qur'an is meant.

Here, it has been said: "We have sent down the Qur'an in the Night of Destiny", and in AI-Baqarah: 185, "Ramadan is the month in which the Qur'an was sent down. " This shows that the night in which the Angel of Allah had brought down revelation for the first time to the Holy Prophet (upon whom be Allah's Peace) in the Cave of Hira, was a night of the month of Ramadan. This night has been described as Lailat-ul-qadr here and as Lailat-im-mubarakah in Surah Ad-Dukhan: 3 above.

2. The commentators in general have understood this to mean that the good acts performed in this Night are superior in value to the good acts of a thousand months in which Lailat-ul-qadr is not included.

But, the verse does not say: "To act righteously in Lailat-ul-qadr is better than acting righteously in a thousand months, " but it says: lailat-ul-qadr is better than a thousand months. " And "a thousand months" also does not imply 83 years and 4 months exactly, but a very long period of time as "a thousand" denoted among the Arabs. Therefore, the verse means that in this one night a task was accomplished for the welfare of mankind the like of which had not been accomplished even during an indefinitely long period of history.

3. "The Spirit": Gabriel (peace be on him), who has been mentioned separately from the angels in view of his unique eminence, honor and merit.

4. That is, they do not descend of their own accord but by leave of their Lord, and "every decree" implies amr hakim (a wise decree) as described in Ad-Dukhan: 5.

5. That is, the entire Night, from evening till morning, is peace, free from every evil and mischief.

Ahadith

[Sahih Bukhari : Volume 3, Book 32 "Taraweeh", Number 232]

Narrated Ibn 'Umar (Radi Allah Anhu) : Some men amongst the companions of the Prophet Muhammad (sal-allahu- alleihi-wasallam ) were shown in their dreams that the night of Qadr was in the last seven nights of Ramazan. Allah's Messenger (sal-allahu- alleihi-wasallam ) said, "It seems that all your dreams agree that (the Night of Qadr) is in the last seven nights, and whoever wants to search for it should search in the last seven nights of Ramazan."

[Sahih Bukhari : Volume 3, Book 32 "Taraweeh", Number 233]

Narrated Abu Salama (Radi Allah Anhu) : I asked Abu Sa'id (Radi Allah Anhu) about the Night of Qadr and he said, "We practised Itikaf in the middle third month of Ramazan with Prophet Muhammad (sal-allahu- alleihi-wasallam ). In the morning of the 20th of Ramazan, the Prophet Muhammad (sal-allahu- alleihi-wasallam ) came to and addressed us and said, "I was informed of the date of the Night of Qadr but I was caused to forget it, or I forget, so search it in the last ten nights of month of Ramazan."

Narrated 'Ibn Abbas (Radi Allah Anha): The Allah's Messenger (sal-allahu- alleihi-wasallam ) said:
"Look for the Night of Qadr in the last ten nights of Ramazan on the night when nine or seven or five nights remain out of the last ten nights of the Ramazan."

Narrated 'Ibn Abbas (Radi Allah Anha) in this quotation: Allah's Messenger (sal-allahu- alleihi-wasallam ) said:
"The Night of Qadr is in the last ten nights of the month of Ramazan either on the first nine or in the last (remaining) seven nights of Ramazan."

Narrated 'Aisha (Radi Allah Anhu) : With the start of the last ten days of Ramazan, Allah's Messenger (sal-allahu- alleihi-wasallam ) used to tighten his waist-belt (i.e. hard work) and used to offer Salat (Prayer) all the night, and used to keep his family awake for the Salat (prayers).

Zirr b. Habaish (Radi Allah Anhu) reported Ubayy b. Ka'b (Radi Allah Anhu) took oath (without making any exception, i. e. without saying Innsha Allah) that it was the twenty-seventh night. I said to him: Abu Mundhir, on what ground do you say that? Thereupon he said: By the indication or by the sign which the Messenger of Allah (sal-allahu- alleihi-wasallam ) gave us, and that is that on that day (the sun) would rise without having any ray in it.

Zirr b. Hubaish (Radi Allah Anhu) reported that Ubayy b. Ka'b (Radi Allah Anhu) said about Lailat-ul-Qadr: By Allah, I know well about it. Shu'ba said: To the best of my knowledge it was the twenty-seventh night for which the Messenger of Allah (sal-allahu- alleihi-wasallam ) commanded us to stand for prayer. Shu'ba doubted these words: That it was the night for which the Messenger of Allah (sal-allahu- alleihi-wasallam ) commanded us to stand for prayer. And (he further) said: This was narrated to me by a friend of mine from him (the Holy Prophet).

Abu Huraira (Radi Allah Anhu) reported: We were talking about Lailat-ul-Qadr in the presence of the Messenger of Allah (sal-allahu- alleihi-wasallam ) and he said: "He who amongst you remembers (the night) when the moon arose and it was like a piece of plate (at the fag end of the month in a state of waning)."

informative post...we all should be well aware of this great night of ramadhan...n so we should be praying n asking for forgiveness to Allah for our bad deeds...Signs of Laila tul Qadr are:
1. This night possesses an extraordinary shine and brightness of its own.
2. Taking into account local climate the weather in that night won’t be either cold or warm, i.e. the night temperature will be average for this climate, region and season.
3. This night will be calm, clear and dry.
4. Stars do not fall in that night.
5. The next morning after this night the sun will be bright, brilliant and incarnadine (light-red). Its shine will be tender, not blinding just like the full moon in the clear night.

1. Seeking Forgiveness. Hazrat Aa'ishah radhiyallahu anhaa asked the Prophet sallalahu alayhi wasallam that if she happened to get the night sublime what prayer should she say. The Prophet sallalahu alayhi wasallam replied that she should say the following prayer :

2. Reciting Astaghfar. The following should be recited as much as possible:
"Astaghfirullah hallazi la-ila-ha illa huwal Hayyul Qayyumo wa atu-bu ilaihe"
(I seek forgiveness from Allah, the Almighty, there is no God but He. He is self-Existent, the Eternal and I return to Him)
